Complete enclosure solutions from concept to production, featuring thermoforming, precision fabrication, rapid prototyping, and scalable manufacturing for industrial-grade protection.
Custom vacuum-formed enclosures using eight machines ranging from 2'x3' to 5'x9'. High-volume rotary thermoforming delivers cost-effective protective housings with quick turnaround times for both small and large production runs.
Exact-specification finishing using two 5'x10' CNC trimming centers. Automated routing, drilling, and edge finishing ensure dimensional accuracy and assembly-ready parts for custom enclosures and industrial components.
Expert fabrication of custom enclosures and machine guards with secondary operations including heat bending, bonding, fastener installation, and precision drilling—avoiding most tooling charges while meeting exact specifications.
Custom molds and tooling using CNC-milled wood or polyurethane for prototypes and aluminum castings for production. Low-cost tooling enables rapid design iterations and cost-effective production ramp-up.
Low-cost prototype enclosures produced in weeks using precision wood or polyurethane tooling. Evaluate fit, function, and design before committing to production tooling with rapid iteration capability.
Scalable production from prototyping to thousands of units using advanced 4'x7' rotary thermoforming with 2.5x faster cycle times. Rigorous quality control ensures consistency across large production runs.
Hill Plastics combines 45 years of thermoforming expertise with state-of-the-art CNC fabrication to deliver custom equipment enclosures that protect your critical components. Our turnkey approach guides you from initial design consultation and material selection through rapid prototyping, tooling development, and scalable production. Whether you need ruggedized aerospace housings, telecom radome enclosures, medical device covers, or industrial machine guards, our 20,000 sq ft Texas facility delivers quality-controlled enclosures with competitive pricing and quick turnaround times that keep your projects moving forward.
